(NaturalNews) Researchers have just discovered that flavonoids extracted from common onions slow the rate of colon cancer growth in mice just as effectively as a chemotherapy drug. And while the mice on chemo saw their LDL cholesterol go up (a possible side effect of the drug), the mice on onion extract actually saw their LDL levels drop.

Onion flavonoids slow colon tumor growth by 67% in vivo

In this study, researchers fed three different doses of flavonoids extracted from onion, an oral chemo drug, or saline (as control) to mice, along with a high-fat diet. The fatty diet was used to induce high blood fats and cholesterol (hyperlipidemia), since that is a major risk factor for colon cancer, and many human colon cancer patients have this condition. The highest dose of onion extract slowed the growth of colon tumors by 67% compared to the controls after three weeks…
